Time-balanced multiplexer switching methods and apparatus

摘要

Methods and apparatus are provided for time-balanced switching of multiplexer circuits. An embodiment of the invention includes a transistor chain coupled to the output of the multiplexer circuit. The transistor chain preferably delays transitions that would otherwise occur relatively quickly, to match the timing of transitions that occur relatively slowly. The timing of relatively slow transitions is left unaltered. The invention advantageously allows all selector input transitions to yield a data output transition with a substantially constant delay.
